MECHANICAL MOVEMENT.

SPECIFICATIQN forming part. of Letters Patent No. 323,789, dated August4, 1885.

Application tiled December 3l, 1884. (No model.)

To all whom t may-concern:

Beit known that I, Louis CHEVALLIER, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New' York,have invented new and useful Improvements in Mechanical Movements, ofwhich the following is a specification.

' rlhis invention relates to mechanical movements for transmittingcontinuous rotary motion from one shaft to another; and it consists inthe combination of two shafts, one being the driving-shaft and the otherthe driven shaft, an eccentric mounted on the drivingshaft, an eccentricwrist-pin secured to the driven shaft, a pitman connecting the eccentricof the driving-shaft with the wrist-pin of the driven shaft, a leverwhich acts upon the pitman, and an eccentric or cam mounted onv thedrivingshaft and imparting to the lever a vibrating motion; also, in thecombination of two shafts, one being the driving-shaft and the other thedriven shaft, an eccentric mounted on the driving-shaft, an eccentricwrist-pin secured to the driven shaft, a pitman connecting the eccentricof the driving-shaft with the wrist-pin of the driven shaft, arock-shaft intermediate between the driving-shaft and the driven shaft,and an opening in the rock-shaft for the passage of the pitman; and,also, in the combination of two shafts, one being the driving-shaft andthe other the driven shaft, an eccentric mounted on the driving-shaft,an eccentric wrist-pin secured to the driven shaft, a pitman connectingthe eccentric of the driving-shaft with the wrist-pin of the drivenshaft, a rock-shaft intermediate between the driving-shaft and thedriven shaft, and provided with an opening for the passage of thepitman, a forked lever extending from the rock-shaft, and an eccentricmounted on the driving-shaft and acting on the forked lever.

This invention is illustrated in the accompanying drawings, in whichFigure l is a side elevation, partly in section,showing the position ofthe parts when the wrist-pin is on the lower dead-center. Fig. 2 is aside elevation, partly in section, showing the same when the wrist-pinis in an advanced position. Fig. 3 is a front elevation.

Similar letters indicate corresponding parts. In the drawings, theletters A and B designate the two uprights forming a frame for the partsC is the driving-shaft, and D is the driven shaft, both provided withsuitable bearings in the uprights A B. On the driving-shaft C is theeccentric E, which may be keyed thereon in the usual-manner, or it may Ybe formed integral therewith. The eccentric E is provided with asuitable eccentric-strap,

a, and is connected by means of the pitman b to the eccentric wrist-pinc, formed integral with or secured to the driven shaft D.

On the driving-shaft may be mounted another eccentric or cam; or theeccentric E may,

as shown in the drawings, be made of sufficient breadth to answer thepurpose of both.

F is a lever, formed on its upper end with a fork, d, which is engagedby the eccentric E, and on its lower end with a fork, e, which engagesthe pitman b.

G is a rock-shaft, to which is secured or may be formed integraltherewith the lever F. The rock-shaft is provided with a transversehole, f, for the passage of the pitman b, allowing a longitudinal motionof the same, and has its bearings in center points formed on the ends ofscrews g g', secured in the frame; or other suitable means may beemployed.

It is evident that if the eccentric E were directly connected with theeccentric wristpin c motion of the shafts would be arrested at each ofthe two dead-centers, making a transmission of rotary motion impossible.The object of this invention is to overcome this-d-ifhculty, which isaccomplished by the combination of the aforesaid parts.

By the motion of the eccentric E a vibrating motion is imparted to thelever F, and if the parts are in the position shown in Fig. l, and thedriving-shaft C be slightly moved in the direction of arrow 1, the leverF will swing in the direction of arrow 2, and thereby the wrist-pin c ismoved over the deadcenter to the position shown in Fig. 2, and thermotion of the shafts C D can be continued. If the pitman tits theholefin the rock-shaft G, the rocking motion of this shaft G will beforedescribed, of tvvo shafts, one being the driving-shaft and the other thedriven shaft, un eccentric mounted on the driving-shalt, an eccentricWrist-pin secured to the driven shaft, a pitman connecting the eccentricof the driviugshni't with the wristpin of the driven shaft, :ineccentric or cam on the clriviiigsliztf't, and :t lever v ibrated by theeccentric or cam and loosely connected with the pitman intermediate theeccentric on the driving-shaft and the Wrist-pin on the driven shaft.

2. The combination,substantially as liereinbefore described, of twoshafts, one being the diivingshaft and the othei` the driven shaft, aneccentric mounted on the driving` shaft, an eccentric Wrist-pin securedto the driven shaft, zt pitman connecting1 the eccentric of thedriving-slitf`t with the wrist-pin ofthe driven Shaft, and :t rock-shaftsupported between the driv ing and the driven shaft, and having atrainsverse openi1ig,througl1 which the pitman freely reciprocates.

3. The combination,substantially as hereinl before described, of twoshafts, one being` the driving-shaft and the other the driven Shaft, :ineccentric, mounted on the driving-shaft, an eccentric wrist-pin securedto the driven shaft, :t pitmen connecting the eccentric of the driving-slmft with the Wrist-pin ofthe driven shaft, in rock-shaft between thedriving-shaft and the driven shaft, and provided with it transverseopening. through which the Pitman freely re ciprocutes, a forked leverextending from the rock-shaft, and an eccentric mounted on thedriving-shaft and ztctingou the forked lever.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing,` witnesses.
